Train like Sonnie Trotter

Gosh, this is impressive, note taken!

Comment on You Tube by 'Iluluu':

"One session per week is ok for intermediate climbers. Rest 5 minutes or more, to find yourself ready for the next Campus set.

For endurance is good to do 5 sets of 3 minutes non stop climbing with 1 minute rest between sets.

Train in a way: Day 1 Power (campus, boulders, etc), D2 Endurance, D3 Rest, D4 Power, D5 Endurance, D6 and D7 Rest."
